Re: Where can I get a ringing table from?

I took some side and top view pics that may help show the clearances that are possible on the Leitz table. By moving the ruler around, I would estimate that a glass slide could over-hang the ringing stage/ turn-table by almost 1/2 inch before it would hit the pillar that supports the hand rest. I'll...

Re: My Favorite Microscope Cleaning Pad

I'm glad this has been well received! I will have to concur with Gerard that I do love Kimwipes for this same purpose. When I worked for Carolina Biological, Kimwipes was our go-to cleaner in conjunction with petroleum ether used as both a degreaser and lens cleaner. The nice thing about Kimwipes is...

Re: Where can I get a ringing table from?

I love this post! I have contemplated buying one of the Brunel ringing tables so that I didn't possibly mess up my vintage Leitz table! As I recall, the Brunel tables are very reasonably priced.

Re: B&L Panfocal Illuminator - Milling a New Lamp Housing

While the Needham text references the Panfocal similarity to the Berek condenser, I would have to also mention (from the standpoint of 3 types of illumination) the Leitz Heine condenser which, with the turn of a knurled knob, accommodates rapid transition between bright field, phase contrast, and da...

Re: My Favorite Non-microscope Microscopy Related Tool

If that weren't a Brunel created video, I would assume he just voided the warranty by avoiding that little knurl!!!!!!!!!!!!!!!!!!!!!!!!!!! It's like some little ole lady quilters I know... the knurling helps you develop a "slide ringing callus!"

My Favorite Microscope Cleaning Pad

I buy these 100% cotton makeup pads at Wally World for $1.98/per 100 and cannot recommend them enough. Soak them in a little ethyl ether or lens cleaning solution and you've got the perfect lens wipe.

My Favorite Non-microscope Microscopy Related Tool

I bought this Leitz slide ringing table several years ago and had forgotten I had it. I acquired it in anticipation of making diatom exhibition slides and hope to someday learn how to use it. I surmise that it is the pattern that the Brunel slide ringing table casting is based on... BEAUTIFULLY made...

Re: B&L Panfocal Illuminator - Milling a New Lamp Housing

As a further indication of the complexity of the Panfocal condenser/illuminator, by comparing B&L 1958 price lists, a fairly complete 4 objective Model TT ("tri-ocular") Dynoptic would cost you around $670 USD, the Panfocal Illuminator by itself was listed (from the same source) at a hefty $240 USD!

hello dtsh! I love "the enlighten-ment!"

B&L Panfocal Illuminator - Milling a New Lamp Housing

This Panfocal Illuminator was a recent Fleabay purchase and, as is the case with so many microscope components that are easily removed without tools, it was missing the actual illuminator. I've got some aluminum square stock that I will be milling to fit and an offshore LED illuminator as a lamp and...

That's a good idea, especially with the micrometer eyepiece - it has an unusual diagonal X as the moveable crosshair against the background scale.

$29 Fleabay Microscope Poses for Her Glamour Shots

I literally bought this old cast iron Bausch and Lomb in order to slaughter it out for parts - $29 on Fleabay (the shipping was almost more than the cost of the scope!) Due to the cast iron stage, limb, and foot, she weighs in at a hefty 11lbs. An Ortholux I, by comparison, is around 25lbs, but the ...

I suspect you may be correct. That is one of the more endearing characteristics of most American manufacturing - that they would tend to standardize a part to work in different applications.

So, these are Fleabay "salvage" items that I sortuv agonized buying (in order to fancy up a "triocular" B&L Dynoptic).

Most over-the-counter enamels "bake on" beautifully in an oven at around 200 degrees F. You're gonna have some nasty fumes so BE CAREFUL! Your home oven or a toaster oven are NOT paint ovens and therefore NOT "explosion proof"!!!!
